A quality monitoring system and method for a current transformer testing assembly line

Abstract

The invention discloses a quality monitoring system and method for a current transformer testing assembly line, which includes a quality monitoring center and a plurality of assembly line verification subsystems located in different areas; each assembly line verification subsystem includes an assembly line verification device and has a plurality of test The station and the current transformer test line to be tested, as well as the transfer standard components that are regularly sent to the current transformer test line. The invention uses the quality monitoring center to store the information uploaded by different assembly line verification devices respectively, and judges whether there is an abnormal station error exceeding the preset threshold in each current transformer test assembly line, and performs an abnormal alarm when there is an abnormal station error , and screen out the line number and station number corresponding to the abnormal station error for display. All judgments and alarms are performed by the quality monitoring server, which avoids errors caused by human judgment and saves a lot of labor costs.

Description

technical field [0001] The invention relates to the quality monitoring of an assembly line, in particular to a quality monitoring system and method for a current transformer testing assembly line. Background technique [0002] Low-voltage current transformers are suitable for automated testing due to their special structure and large number of uses. Compared with manual verification, automated assembly line verification greatly reduces the demand for space, personnel and materials, and the verification efficiency is also significantly improved, and more data needs to be processed. [0003] However, in order to ensure the accuracy of the current transformer test of the assembly line, it is necessary to verify the assembly line to ensure the stable operation of the assembly line. However, for now, the current transformer test assembly line is usually a fixed and non-movable device. It is necessary for inspectors to bring instruments and equipment to the site to conduct on-sit...

[0003] However, in order to ensure the accuracy of the current transformer test of the assembly line, it is necessary to verify the assembly line to ensure the stable operation of the assembly line. However, for now, the current transformer test assembly line is usually a fixed and non-movable device. It is necessary for inspectors to bring instruments and equipment to the site to conduct on-site testing, and remote viewing is not possible, and the verification data of all assembly lines can only be judged by on-site records and artificial assembly line quality, which is prone to artificial recording errors and judgment errors, and a lot of waste Human Resources
